OIL-BURNER.

Specification of Letters Patent.

Patented Nov. 11, 1919.

Application filed July 12, 1919. Serial No. 310,388.

To all whom it may concern:

Be it known that I, ADELARD COUTURE, a citizen of the United States, residing at Arctic, in the county of Kent and State of Rhode Island, have invented new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to certain new and useful improvements in an oil burner adapted for the installation in small sized steam and hot water heaters.

The principal object of the invention is to provide a simply constructed and yet efficient burner with improved means for regulating the supply of air thereto and thereby control the proper combustion of the gases at the burner.

The invention broadly consists in a hollow body opened at its top and bottom and inclosing a perforated burner plate and a likewise perforated damper plate underlying the burner plate and adjustable to regulate the size of its openings for controlling the flow of air therethrough, the whole being mounted upon a casing shaped to direct the inflowing air to the burner for supplying the necessary oxygen.

The invention further consists in the features of construction and the arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawings wherein Figure 1 is a vertical section through a heater equipped with the improved burner;

Fig. 2 is a plan view of the oil distributing head;

Fig. 3 is a side elevation thereof, partly in section;

Fig. 4 is a plan View of the burner with the oil supplying pipe removed and Fig. 5 is a horizontal section of the burner immediately belowand looking upwardly toward the damper plate.

Referring more in particular to Fig. 1, the numeral 1 designates the steamor hot water heater of a coal burning type and embodying the usual stoking doorway 2 and the ashpit doorway 3. y

The improved construction comprises a casing support 4 having an air inlet registering with the ashpitdoorway and its upper portion deflected inwardly in the. form of a truncated cone whichis designed to direct the inflowing air toward its central top opening in which the burner is disposed. The burner consists of a cup-shaped hollow body 5 having a peripheral flange 6 seating on the surrounding upper edge of the truncated support. The base or bottom of the cupshaped burner body is suspended, by a pair of arms 7, a distance from the hollow body to provide lateral passageways 8 which establish communication between the interior of the burner and the interior of the casing. Fixed centrally of the base 9 is an upright shaft 10 and on the upper end of this shaft is fixed a collar 11 that constitutes a support for a damper plate 12 and a superposed burner plate 13, the burner plate may be secured to the shaft 10 if desired, said plates being supported in a plane above the air inlet openings 8 of the burner. Both plates are provided with a plurality of perforations 14 adapted to register and whose registry is controlled by means of an operating pin 15 carried by the damper plate and extending upwardly through a short arcuate slot 16 in the burner plate. The upper face of the burner plate is given a dished effect by forming the same with bosses or protuberances 17 through which the perforations pass.

I The liquid fuel is supplied to the burner through a pipe 18 connected to a suitable supply, not shown, and conveniently passing through the ashpit doorway and up through the casing from whence a horizontal heating pipe 19 leads over the burner and centrally suspends the oil distributing head 20.

,This head has a peripheral series of oilconducting grooves 21 for directing the oil to the exterior, downwardly flaring surface of the head. The lower end of the head is cupped to fit over'a central hub extension of the burner plate .to serve in steadying and keeping the latter in position.

In operation, the oil is distributed by the head 20 over the central portion of the burner plate from whence the oil spreads radially and up over the bosses 17 about the air openings. The air is forced centrally bv the conical casing'or support and. therefore issues 'from the openings in the burner plate in strong jets. By adjustment of the damper plate the size of the openings may be regulated and thus the jets of air may be controlled. The oil in passing through the horizontal pipe 19 becomes heated to aid its combustion on the burner plate so that after the burner has been started the air openingsof the burner plate may be opened to a greater extent. I

the heater or furnace construction.

' Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. An oil burner comprising a casing adapted to be inserted in the ashpit of; a heater and having a truncated upper portion, a burner body formed with a peripheral flange seating on the upper edge of the truncated portion of the casing, said body having lateral openings establishing communication between the interior of the body and the casing, a shaft fixed centrally on the base of the body and extending up- 1 wardly therein, a collar fixed on the upper end of the shaft, a damper plate rotatable on the shaft and collar, a superposed burner plate on the damper plate, said plates formed with registrable apertures, means for adjusting the damper plate to open and close the apertures of the burner plate, and means for supplying oil to the burner plate.

2. An oil burner comprisin a hollow support, a cupshaped burner boc y mounted on the support and having its lower portion formed with lateral passages communicating with the interior of the support, an upstanding shaft on the base of the body, a

,damper plate journaled on the upper end of y the shaft above the lateral passages, a.

burner plate superposed on the damper plate and fixed to the shaft, said plates formed with registrable perforations, and means for-supplying oil to .the burner plate.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
